OK, I walked in a little late to the first AoIR 2011 presentation this morning, by Michele Willson, whose focus is on information filtering. There are different approaches to such filtering: at the user or at the service end, initiated by users or by the system, cognitive or social filtering, and based on knowledge about the user’s interests which may be acquired through a range of different mechanisms.
Different stakeholders in the process, and in developing these processes, will have a range of different agendas and interests – developers have specific algorithms they may wish to explore, funding bodies and sources have specific commercial or other imperatives, users and their friends are interested in particular forms of online activity (content sharing, phatic communication, etc.), and the social network providers overall are interested in increasing participant numbers and boost the stickiness of the platform.
